forms the inner epithelium .
1. lines all body sufaces , inside and out
2. lines the lumen of blood vessals , ducts , body cavities as well as surfaces of respitory , digestive, urinary, and reproductive tracts.
3. forms outer layer of skin
1. forms the secreting portion of glands and ducts
2. includes both exocrine glands that secret substances outside the body including lumens and endocrine glands that secret substances in blood stream
!. Apical/ free space
2. cell mass
3. basal surface
4. basement membrane
what are the four types of cell chapes?
irregularly shaped cells with round nuclei
they are found in organs that strectch like the urinary bladder
filtration, osmosis, diffusion, and secretion.
what are the function of the simple squamous epithelium?
what does the cells look like through a microscope?
located in moist areas such as vagina, mouth , nose.
function is to lubricate and protect
also , you see cells throughout the whole cell going up
location is in hair, nails and skin
function is protection
membrane is cutaneous
also, the cells are died off at the top of the cell and sometimes a white layer is shown.
location: kidney tubule, ovarie lining
function:secretion and absorption
these cells look like cheroos and have an opening and the inside has circles in it
collective term for microvilli; the ribbion of micro villi that is obvious in all slides
located gi tract
function is absorption and secretion
has a mucous membrane
has microvilli and goblet cells
its non-ciliated bc it doesnt have movement ontop cell
located lining of the lungs
function is movement and secretion
has mucous membrane
location is uretha
function is stretching
has a whole in middle or space
the narrow range of values between which life can be sustained
this detects a stimuus and monitors it.
-you find this receptor in your skin, eyes, nose
this evaluates information'
- this is also found in your brain and spinal cord
this recieves a signal from the control center and responds to bring a change
- causes a change back to normal or away
this occurs when deviations from normal are corrected.
these are common in the body and are used for conditions that need frequent adjustments.
occurs when deviations from normal are encourages and the original stimuus is intensified.
this is less common
what are the functions of the nervous system?
ex:right leg right arm
- abdomen (abdominal region)
- pelvis (pelvic region)
4. upper limbs
5. lower limbs
1. umblical (navel)
what are the markings in the abdomen region?
1. cranial cavity
2. spinal cavity
whats in the dorsal body cavity?
what type of membranes are these cavities lined wih?
A. mediastinum-touches heart
B> pericardial cavity- surrounds heart
C. pleural cavity-surrounds lungs
2. pelvic cavity
what are the abdominopelvic regions?
1. right u. quadrant
2. right l. quadrant
3. l upper quad
4. left lower quad.
- has cell and matrix
- no free space
- innervted except cartliage
- generally avascular except tendons
binds components of ground substance together
lubricates joints and maintains shape of eye
provides support and adhesion for cartliage
